30-4-2019 MONTE CORONA, VALENCIA - WESTERN HONEY BEE ( Apis mellifera)
%2020.jpg)
The western honey bee (\(Apis\ mellifera\)) is a vital insect known for honey production and pollination, native to Europe, Asia, and Africa, but now found on every continent except Antarctica thanks to humans. Each colony has a single queen, numerous sterile female worker bees, and male drones, with the queen laying thousands of eggs daily. These bees are crucial for many ecosystems and agricultural crops, and they have a complex social structure that includes communication through the "waggle dance" to share food source locations.
Colony structure and roles Queen: The only reproductive female, she can lay up to 2,000 eggs per day and lives for several years.
Workers: Sterile females that perform all labor, including foraging for nectar and pollen, building and cleaning the hive, and caring for the young.
Drones: Male bees whose sole purpose is to mate with a queen.
%2021.jpg)
Brood: Offspring of the queen that are cared for by worker bees. Eggs hatch into larvae, which are fed and then develop into pupae before becoming adults.
Communication and behavior Waggle dance: A famous communication method where foraging bees can tell other bees the direction and distance to a food source.
Foraging: Worker bees collect nectar and pollen, which are visible on their hind legs in pollen baskets, and store honey in hexagonal cells within the hive.Water collection: Older worker bees collect water to help cool the hive and for various other uses within the colony.
%2022.jpg)
Reproduction and life cycle Reproduction: The queen is the sole reproductive female; other females are sterile workers.Drones: These males mate with future queens during mating flights. Drones cannot feed themselves and are incapable of stings.Development: Eggs hatch into larvae in three days. After being fed by nurse bees, larvae develop into pupae and then emerge as adult bees about 21 days after the egg was laid.
Queen: A queen starts as a fertilized worker egg and is fed a special diet called royal jelly, which causes her to develop into a queen. Global distribution Native to Europe, Africa, and the Middle East, western honey bees have been introduced by humans to every continent except Antarctica.Humans introduced them to North America in the early 1600s and later to South America, Australia, New Zealand, and East Asia. Importance and threats
Pollination: Western honey bees are crucial pollinators for many food crops and ecosystems around the world.Threats: They face significant threats from pests like the Varroa mite, diseases, and colony collapse disorder.IUCN Red List: As of 2019, they were listed as "Extinct" on the IUCN Red List, though further research is needed to determine the conservation status of wild populations versus managed colonies.
30-4-2019 MARXUQUERA, VALENCIA - EURASIAN HOOPOE (Upupa epops)
The Eurasian hoopoe (Upupa epops ) is the most widespread species of the genus Upupa. It is a distinctive cinnamon coloured bird with black and white wings, a tall erectile crest, a broad white band across a black tail, and a long narrow downcurved bill. Its call is a soft "oop-oop-oop". It is native to Europe, Asia and the northern half of Africa. It is migratory in the northern part of its range. It spends most of the time on the ground probing for grubs and insects. The clutch of seven to eight eggs is laid in an existing cavity. The eggs are incubated by the female and hatch asynchronously. Some ornithologists treat the African and Madagascar hoopoes as subspecies of the Eurasian hoopoe.
The Eurasian hoopoe is a cinnamon-colored bird with black and white wings, a tall erectile crest, a broad white band across a black tail, and a long narrow downcurved bill. The bird has broad and rounded wings capable of strong flight which are larger in the northern migratory subspecies. The hoopoe has a characteristic undulating flight, which is like that of a giant butterfly, caused by the wings half-closing at the end of each beat or a short sequence of beats.
Eurasian hoopoes are widespread in Europe, Asia, and North Africa, and northern Sub-Saharan Africa. Most European and north Asian birds migrate to the tropics in winter. Those breeding in Europe usually migrate to the Sahel belt of sub-Saharan Africa. The African populations are sedentary all year. Eurasian hoopoes require bare or lightly vegetated ground on which to forage and vertical surfaces with cavities (such as trees, cliffs, or even walls, nestboxes, haystacks, and abandoned burrows) in which to nest. These requirements can be provided in habitats such as heathland, wooded steppes, savannas and grasslands, as well as forest glades.

29-4-2019 TORMOS, ALICANTE - HOUSE SPARROW (MALE) (Passer domesticus)
The house sparrow (Passer domesticus) is a member of the sparrow family Passeridae. This small bird typically measures around 16 cm (6.3 in) in length and weighs between 24–39.5 g (0.85–1.39 oz). The species exhibits sexual dimorphism, with females and young birds displaying pale brown and grey plumage, while males are characterized by more vibrant black, white, and brown markings.
Males can be identified by their bright black, white, and brown markings, with a distinctive black bib, white cheeks, and a grey crown. Females lack the striking head patterns of males and are predominantly buffish with softer coloration. Juveniles resemble adult females but are generally paler with less defined markings.
The house sparrow is highly adaptable and can thrive in both urban and rural environments. It is commonly found in close association with human habitation and avoids dense forests, grasslands, polar regions, and deserts far from human development.
Native to Europe, the Mediterranean Basin, and much of Asia, the house sparrow has been introduced to various regions worldwide, including parts of Australasia, Africa, and the Americas, making it one of the most widely distributed wild birds.
House sparrows are social birds, often seen in flocks. They exhibit a range of behaviors, including dust or water bathing and communal roosting. Males are known to be territorial around their nesting sites.
The house sparrow's vocalizations are predominantly variations of a simple chirping call. Males may sing or give an "ecstatic call" during the breeding season, and the species uses a variety of calls for different social interactions.
House sparrows are generally monogamous and may mate for life. They can breed in the season following their hatching and often produce multiple clutches per year, with each clutch containing up to five eggs. Nest sites are varied, with a preference for cavities.
An opportunistic feeder, the house sparrow's diet consists mainly of seeds from grains and weeds, but it also consumes insects and other invertebrates, especially during the breeding season when feeding young.

28-4-2019 MONTE CORONA, VALENCIA - BOX BUG (Gonocerus acuteangulatus)
%2020.jpg)
Gonocerus acuteangulatus is a herbivorous species of true bug in the family Coreidae. It is commonly known as the box bug in the UK as it once only occurred in Box Hill in Surrey where it fed on box trees.
This species was formally described by the German zoologist Johann Goeze in 1778, under the name Cimex acuteangulatus.
This species commonly occurs throughout the Mediterranean region and extends to Central Asia and parts of northwestern Europe.
These heat-loving bugs inhabit mainly dry and warm, south-exposed environments, bushes and forest edges with shrubs that bear berries and small trees of various families, especially Buxaceae and Rhamnaceae, as well as Rosa canina and Crataegus species (Rosaceae) or Lonicera xylosteum (Caprifoliaceae).
%2021.jpg)
Gonocerus acuteangulatus is a medium-sized insect, between 11 and 14 mm long as an adult. These bugs are speckled reddish-brown with a slightly expanded abdomen. The nymphs have a green abdomen. This species is rather similar to Coreus marginatus, but it shows a narrower abdomen and has sharper lateral margins of the pronotum (hence the Latin species name acuteangulatus).
Adults can be found all year. They mainly feed on the juice of the ripe fruits of the host plants. This species is a harmful pest of the hazel and pistachio. It can also be a vector of the fungus Nematospora coryli, an agent of stigmatomycosis.
28-4-2019 PALMA DE GANDIA, VALENCIA - MALLARD (JUVENILE) (Anas platyrhynchos)
The mallard (/ˈmælɑːrd, ˈmælərd/) or wild duck (Anas platyrhynchos) is a dabbling duck that breeds throughout the temperate and subtropical Americas, Eurasia, and North Africa. It has been introduced to New Zealand, Australia, Peru, Brazil, Uruguay, Argentina, Chile, Colombia, the Falkland Islands, and South Africa. This duck belongs to the subfamily Anatinae of the waterfowl family Anatidae. Males have green heads, while the females (hens or ducks) have mainly brown-speckled plumage. Both sexes have an area of white-bordered black or iridescent purple or blue feathers called a speculum on their wings; males especially tend to have blue speculum feathers. The mallard is 50–65 cm (20–26 in) long, of which the body makes up around two-thirds the length. The wingspan is 81–98 cm (32–39 in) and the bill is 4.4 to 6.1 cm (1.7 to 2.4 in) long. It is often slightly heavier than most other dabbling ducks, weighing 0.7–1.6 kg (1.5–3.5 lb). Mallards live in wetlands, eat water plants and small animals, and are social animals preferring to congregate in groups or flocks of varying sizes.
The female lays 8 to 13 creamy white to greenish-buff spotless eggs, on alternate days. Incubation takes 27 to 28 days and fledging takes 50 to 60 days. The ducklings are precocial and fully capable of swimming as soon as they hatch.
The mallard is considered to be a species of least concern by the International Union for Conservation of Nature (IUCN). Unlike many waterfowl, mallards are considered an invasive species in some regions. It is a very adaptable species, being able to live and even thrive in urban areas which may have supported more localised, sensitive species of waterfowl before development. The non-migratory mallard interbreeds with indigenous wild ducks of closely related species through genetic pollution by producing fertile offspring. Complete hybridisation of various species of wild duck gene pools could result in the extinction of many indigenous waterfowl. This species is the main ancestor of most breeds of domestic duck, and its naturally evolved wild gene pool has been genetically polluted by the domestic and feral mallard populations.
28-4-2019 GANDIA MARJAL, VALENCIA - COMMON SLIDER TERRAPIN (Trachemys scripta)
The red-eared slider or red-eared terrapin (Trachemys scripta elegans) is a subspecies of the pond slider (Trachemys scripta), a semiaquatic turtle belonging to the family Emydidae. Native to the southern United States and extreme northern Mexico, it is popular as a pet across the world, and is the most invasive turtle. It is the most commonly traded turtle in the world.
The red-eared slider is native to the Midwestern United States and northern Mexico, but has become established in other places because of pet releases, and has become invasive in many areas where it outcompetes native species. The red-eared slider is included in the list of the world's 100 most invasive species.
Red-eared slider young look practically identical regardless of their sex, making distinguishing them difficult. One useful method, however, is to inspect the markings under their carapace, which fade as the turtles age. Distinguishing the sex of adults is much easier, as the shells of mature males are smaller than those of females. Male red-eared sliders reach sexual maturity when their carapaces' diameters measure 10 cm (3.9 in) and females reach maturity when their carapaces measure about 15 cm (5.9 in). Both males and females reach sexual maturity at 5–6 years old. Males are normally smaller than females, although this parameter is sometimes difficult to apply, as individuals being compared could be of different ages.
Males have longer claws on their front feet than the females; this helps them to hold onto a female during mating, and is used during courtship displays. The males' tails are thicker and longer. Typically, the cloacal opening of a female is at or under the rear edge of the carapace, while the male's opening occurs beyond the edge of the carapace. The male's plastron is slightly concave, while that of the female is completely flat. The male's concave plastron also helps to stabilize the male on the female's carapace during mating. Older males can sometimes have a dark greyish-olive green melanistic coloration, with very subdued markings. The red stripe on the sides of the head may be difficult to see or be absent. The female's appearance is substantially the same throughout her life.
The red-eared slider originated from the area around the Mississippi River and the Gulf of Mexico, in warm climates in the Southeastern United States. Their native areas range from the southeast of Colorado to Virginia and Florida. In nature, they inhabit areas with a source of still, warm water, such as ponds, lakes, swamps, creeks, streams, or slow-flowing rivers.
They live in areas of calm water, where they are able to leave the water easily by climbing onto rocks or tree trunks so they can warm up in the sun. Individuals are often found sunbathing in a group or even on top of each other. They also require abundant aquatic plants, as these are the adults' main food, although they are omnivores. They are, however, carnivorous as juveniles as they require a high protein intake for growth.Turtles in the wild always remain close to water unless they are searching for a new habitat or when females leave the water to lay their eggs.
Invasive red-eared sliders cause negative impacts in the ecosystems they are introduced to because they have certain advantages over the native populations, such as a lower age at maturity, higher fecundity rates, and larger body size, which gives them a competitive advantage at basking and nesting sites, as well as when exploiting food resources. They also transmit diseases and displace the other turtle species with which they compete for food and breeding space.
28-4-2019 GANDIA MARJAL, VALENCIA - HOUSE SPARROW (FEMALE) (Passer domesticus)
The house sparrow (Passer domesticus) is a member of the sparrow family Passeridae. This small bird typically measures around 16 cm (6.3 in) in length and weighs between 24–39.5 g (0.85–1.39 oz). The species exhibits sexual dimorphism, with females and young birds displaying pale brown and grey plumage, while males are characterized by more vibrant black, white, and brown markings.
Males can be identified by their bright black, white, and brown markings, with a distinctive black bib, white cheeks, and a grey crown. Females lack the striking head patterns of males and are predominantly buffish with softer coloration. Juveniles resemble adult females but are generally paler with less defined markings.

House sparrows are generally monogamous and may mate for life. They can breed in the season following their hatching and often produce multiple clutches per year, with each clutch containing up to five eggs. Nest sites are varied, with a preference for cavities.
The house sparrow can be confused with other seed-eating birds, such as the Eurasian tree sparrow, which has a chestnut crown and a black cheek patch.
An opportunistic feeder, the house sparrow's diet consists mainly of seeds from grains and weeds, but it also consumes insects and other invertebrates, especially during the breeding season when feeding young.
Despite its widespread distribution and abundance, the house sparrow has experienced declines in some areas. However, it is currently listed as Least Concern on the IUCN Red List.
28-4-2019 GANDIA MARJAL, VALENCIA - LITTLE EGRET (Egretta garzetta)
The Little egret (Egretta garzetta) is small elegant heron in the family Ardeidae. As an aquatic bird, it feeds in shallow water and on land, consuming a variety of small creatures. At one time common in Western Europe, the Little heron was hunted extensively in the 19th century to provide plumes for the decoration of hats and became locally extinct in Northwestern Europe and scarce in the south. Around 1950, conservation laws were introduced in southern Europe to protect the species and their numbers began to increase.
The plumage of the Little egret is normally entirely white, although there are dark forms with largely bluish-grey plumage. In the breeding season, the adult has two long plumes on the nape that form a crest. These plumes are about 150 mm (6 in) and are pointed and very narrow. There are similar feathers on the breast, but the barbs are more widely spread.
The Little Egret is a small white heron with attractive white plumes on crest, back and chest, black legs and bill and yellow feet. It first appeared in the UK in significant numbers in 1989 and first bred in Dorset in 1996. Its arrival followed naturally from a range expansion into western and northern France in previous decades. It is now at home on numerous south coast sites, both as a breeding species and as a winter visitor.
With its yellow feet, which are used to flush prey when feeding in shallow water, the Little Egret is a distinctive member of the heron family.
Little Egrets first bred in Britain in 1996 and since then have successfully colonised much of southern Britain and Ireland. Most of the breeding colonies have been established within existing Grey Heron colonies, the two species nesting alongside one another.
The winter distribution is also currently restricted to the southern half of Britain & Ireland, despite the fact that young birds are known to move some distance from their natal site.
15-4-2018 CHOBE NAT PARK, BOTSWANA - SOUTHERN GROUND HORNBILL (Bucorvus leadbeateri)
The Southern Ground Hornbill (Bucorvus leadbeateri), formerly known as Bucorvus cafer, is a remarkable bird, the largest in the hornbill order and found exclusively within Africa. This majestic creature, with a length ranging from 90 to 129 cm and a wingspan of 1.2 to 1.8 meters, is a sight to behold. The males, larger than the females, can weigh between 3.5 to 6.2 kilograms, while females range from 2.2 to 4.6 kilograms. They are predominantly black with striking red patches of bare skin on the face and throat, which serve to keep dust from their eyes while foraging. In flight, the white tips of their wings are distinctly visible. The beak is robust, black, and slightly curved, with a casque more pronounced in males. Females are identified by their violet-blue throat skin, while juveniles have a paler, greyish patch instead of the vibrant red.
To identify the Southern Ground Hornbill, look for its large size, black plumage, and the vivid red or violet-blue skin on the throat. The male's throat is a pure red, while the female's is deep violet-blue. Juveniles can be recognized by their duller grey throat patch. In flight, the white primary feathers are a key distinguishing feature.
The Southern Ground Hornbill is found in woodlands and savannas, requiring a habitat with large trees for nesting and short grass for foraging.
This species ranges from Kenya to South Africa, with its presence also noted in northern Namibia and Angola to southern Zimbabwe and Burundi.
Living in groups of 5 to 10, these birds are apex predators and play a crucial ecological role. They forage on the ground, hunting a variety of prey from insects to small mammals. They are known for their loud, chorus-like calls that can be heard over great distances, serving as a means of maintaining their territory.

26-4-2019 PEGO MARJAL, ALICANTE - ROSE EVENING PRIMROSE (Oenothera rosea)
Oenothera rosea, also known as rosy evening-primrose, rose evening primrose, pink evening primrose, or Rose of Mexico, is a plant belonging to the genus Oenothera and native to northern Mexico and Texas.
Oenothera rosea has flowers with less than 2.5 cm (0.98 in) diameter. The shade varies from pink to red.
24-4-2019 MONTE CORONA, VALENCIA - EURASIAN COLLARED DOVE (Streptopelia decaocto)
The Eurasian collared dove, collared dove or Turkish dove (Streptopelia decaocto) is a dove species native to Europe and Asia; it was introduced to Japan, North America and islands in the Caribbean.
The Eurasian collared dove is not migratory, but is strongly dispersive. Over the last century, it has been one of the great colonisers of the bird world, travelling far beyond its native range to colonise colder countries, becoming a permanent resident in several of them. Its original range at the end of the 19th century was warm temperate and subtropical Asia from Turkey east to southern China and south through India to Sri Lanka. In 1838 it was reported in Bulgaria, but not until the 20th century did it expand across Europe, appearing in parts of the Balkans between 1900 and 1920, and then spreading rapidly northwest, reaching Germany in 1945, Great Britain by 1953 (breeding for the first time in 1956), Ireland in 1959, and the Faroe Islands in the early 1970s.
Subsequent spread was 'sideways' from this fast northwestern spread, reaching northeast to north of the Arctic Circle in Norway and east to the Ural Mountains in Russia, and southwest to the Canary Islands and northern Africa from Morocco to Egypt, by the end of the 20th century. In the east of its range, it has also spread northeast to most of central and northern China, and locally (probably introduced) in Japan. It has also reached Iceland as a vagrant (41 records up to 2006), but has not colonised successfully there.
The Eurasian collared dove is a medium-sized dove, distinctly smaller than the wood pigeon, similar in length to a rock pigeon but slimmer and longer-tailed, and slightly larger than the related European turtle dove, with an average length of 32 cm (13 in)[14] from tip of beak to tip of tail, with a wingspan of 47–55 cm (19–22 in), and a weight of 125–240 g (4.4–8.5 oz). It is grey-buff to pinkish-grey overall, a little darker above than below, with a blue-grey underwing patch. The tail feathers are grey-buff above, and dark grey and tipped white below; the outer tail feathers are also tipped whitish above. It has a black half-collar edged with white on its nape from which it gets its name. The short legs are red and the bill is black.
The iris is red, but from a distance the eyes appear to be black, as the pupil is relatively large and only a narrow rim of reddish-brown iris can be seen around the black pupil. The eye is surrounded by a small area of bare skin, which is either white or yellow. The two sexes are virtually indistinguishable; juveniles differ in having a poorly developed collar, and a brown iris. The subspecies S. d. xanthocycla differs in having yellow rather than white eye-rings, darker grey on the head and the underparts a slightly darker pink.
The song is a goo-GOO-goo. The Eurasian collared dove also makes a harsh loud screeching call lasting about two seconds, particularly in flight just before landing. A rough way to describe the screeching sound is a hah-hah.
Eurasian collared doves cooing in early spring are sometimes mistakenly reported as the calls of early-arriving common cuckoos and, as such, a mistaken sign of spring's return.
26-4-2019 PEGO MARJAL, ALICANTE - FIELD BINDWEED (Convolvulus arvensis)
Convolvulus arvensis, or field bindweed, is a species of bindweed in the Convolvulaceae native to Europe and Asia. It is a rhizomatous and climbing or creeping herbaceous perennial plant with stems growing to 0.5–2 metres (1.6–6.6 ft) in length. It is usually found at ground level with small white and pink flowers.
Other common names, mostly obsolete, include lesser bindweed, European bindweed, withy wind (in basket willow crops), perennial morning glory, small-flowered morning glory, creeping Jenny, and possession vine.
Convolvulus arvensis is a perennial vine that typically climbs to 1 metre (3.3 ft). The vine produces woody rhizomes from which it resprouts in the spring, or when the aboveground vines are removed.
The leaves are spirally arranged, linear to arrowhead-shaped, 2–5 cm (0.79–1.97 in) long and alternate, with a 1–3 cm (0.39–1.18 in) petiole. The flowers are trumpet-shaped, 1–2.5 cm (0.39–0.98 in) diameter, white or pale pink, with five slightly darker pink radial stripes. Flowering occurs in the mid-summer (in the UK, between June and September) when white to pale pink, funnel-shaped flowers develop. Flowers are approximately 0.75–1 in (1.9–2.5 cm) across and are subtended by small bracts. Fruit are light brown, rounded and 0.125 inches (3.2 mm) wide. Each fruit contains 2 or 4 seeds that are eaten by birds and can remain viable in the soil for decades. The stems climb by twisting around other plant stems in a counter-clockwise direction.
26-4-2019 PEGO MARJAL, ALICANTE - SCARLET PIMPERNEL (Lysimachia arvensis)
Lysimachia arvensis, syn. Anagallis arvensis, commonly known as scarlet pimpernel, red pimpernel, red chickweed, poor man's barometer, poor man's weather-glass, shepherd's weather glass or shepherd's clock, is a species of low-growing annual plant with brightly coloured flowers, most often scarlet but also bright blue and sometimes pink. The native range of the species is Europe and Western Asia and North Africa. The species has been distributed widely by humans, either deliberately as an ornamental flower or accidentally. L. arvensis is now naturalised almost worldwide, with a range that encompasses the Americas, Central and East Asia, the Indian Subcontinent, Malesia, the Pacific Islands, Australasia and Southern Africa.
This common European plant is generally considered a weed and is an indicator of light soils, though it grows opportunistically in clay soils as well. The origin of the name pimpernel comes from late Middle English pympernele [1400–50], derived from Middle French pimprenelle, from Old French piprenelle, and ultimately from Vulgar Latin *piperīnella (piper 'pepper' + -īn- '-ine' + -ella diminutive suffix).
The flower serves as the emblem of the fictional hero the Scarlet Pimpernel.
When found as a summer annual, the scarlet pimpernel has a low-growing creeping habit, but as a winter annual, it forms a half-rosette with an upright stem. It has weak sprawling stems with square cross-section growing to about 5–30 centimetres (2–12 in) long. They bear bright green, soft, ovate sessile leaves in opposite pairs. The orange, red or blue, radially symmetric flowers, about 10–15 millimetres (0.4–0.6 in) in diameter, are produced singly in the leaf axils from spring to autumn. The petal margins are somewhat crenate and have small glandular hairs. The stamens have lollipop hairs and therefore attract a variety of pollinators, especially flies, but the flowers are also capable of autopollination. The dehiscent capsule fruits ripen from August to October in the northern hemisphere. The weight of the fruiting body bends the stem, and the seeds are transported by the wind or rain. Blue-flowered plants (treated as L. arvensis f. azurea by some sources) are common in some areas, such as the Mediterranean region, and should not be confused with the related blue pimpernel, Lysimachia foemina. In 2007, a molecular phylogenetic study showed that Lysimachia foemina is more closely related to Lysimachia monelli than to Lysimachia arvensis, and should be treated as a separate species (all three species were then placed in Anagallis). The species has a diploid chromosome count of 2n=40.
Scarlet pimpernel flowers open only when the sun shines, and even close in overcast conditions. This habit leads to names such as "shepherd's weather glass". It has been observed along the verges of salted roads, creating a broad red band along the roadside.

24-4-2019 CREU DE LONGA, VALENCIA - LITTLE STINT (Calidris minuta)
The Little Stint, scientifically known as Calidris minuta, is a diminutive wader, a member of the family Scolopacidae. It is recognized by its small stature, fine dark bill, and dark legs, which set it apart from other waders, save for its close relatives, the dark-legged stints. This species exhibits a fine bill tip, unwebbed toes, and a notable long primary projection.
This bird nests on a scrape in bare ground, laying 3–5 eggs. It is polygamous, and male and female may incubate separate clutches.
Food is small invertebrates picked off the mud.
In breeding plumage, the adult Little Stint can be identified by an orange hue on the breast, a stark white throat, and a pronounced white V on the back. Winter plumage makes identification more challenging, while juveniles can be spotted by their pale crown stripes and a faintly pinkish breast. The bird's call is a distinctive sharp "stit."
The Little Stint is found in arctic regions during the breeding season, favoring open, bare ground for nesting.
A true long-distance migrant, the Little Stint breeds in the arctic realms of Europe and Asia. When not breeding, it travels extensively to wintering grounds in Africa and south Asia. It has also been recorded as a vagrant in North America and Australia.
The Little Stint is known for its gregarious nature during the non-breeding season, often forming substantial flocks with other Calidris waders, particularly the Dunlin. These flocks are commonly seen on coastal mudflats or at the edges of inland pools.
Polygamous by nature, the Little Stint lays 3-5 eggs in a scrape on the ground. Both males and females may incubate separate clutches, a unique aspect of their breeding behavior.
The diet of the Little Stint consists of small invertebrates, which it picks off from the mud.
The Little Stint is currently listed as Least Concern by the IUCN, indicating that it is not at immediate risk of population decline. However, its numbers are influenced by the population dynamics of lemmings, which in turn affect predation rates by other Arctic species. The Little Stint is also protected under the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA).
